Title: Mobile radio system
Inventor: HASHIZUME MASAO
IPC: H04Q7/30
Filed: 1986-09-26
Abstract: PURPOSE:To decrease the number of base stations greatly by constituting a radio zone which is larger and larger as speech density is lower and lower and making the traffic of a speech in each radio zone constant. CONSTITUTION:Plural small radio zones equipped with one base station having a means which sends out a control signal for setting the transmission output of mobile stations according to the speech density, and plural mobile stations having means which set their transmission outputs based upon the control signal sent out of the base station are combined. Narrow radio service areas like radio zones 10A and 10B are secured for base stations 1A and 1B arranged in areas where speech intensity is relatively high and wide radio service areas like radio zones 10C and 10D are secured for base stations 1C and 1D arranged in areas where the speech density is low. Consequently, radio service which ranges over a wide area is realized by this mobile radio system by using an extremely small number of base stations 1.

Title: Displacement transducer
Inventor: MIKURIYA KENTA
IPC: G01C3/00
Filed: 1985-10-09
Abstract: PURPOSE:To automatically measure the quantity of the displacement of the surface to be measured by using a point light source, arranging a photosensor with a dead zone in equivalently the same position as that of the point light source and utilizing the output of the photosensor as the feedback signal of an autofocus mechanism. CONSTITUTION:Since a photosensor 8 is provided with a dead zone, when the spot diameter of reflected light is decreased when in focus, most part of the reflected light falls on the dead zone and the output of the photosensor is minimized. Since the output of the photosensor 8 is thus changed in accordance with the position of the surface 3 to be measured when the photosensor 8 having the dead zone in part of a light receiving surface is positioned in equivalently the same position as that of a point light source 7, an in-focus condition can be known from the output of the photosensor 8. When an autofocus mechanism having the output of the photosensor 8 as a feedback signal is constituted, a lens 2 or the like can be displaced such that the light beam emitted from the point light source 7 is always focused on the surface 3 to be measured and the quantity of the displacement of the surface 3 can be automatically measured from the quantity of the displacement of the lens 2 or the like.

Abstract: PURPOSE:To detect a tack bead with good accuracy by comparing with a preset reference value the difference in the integration values found from the arc voltage or welding current waveform detected at two points and right and left points in the welding progressing direction in a high speed rotary arc welding. CONSTITUTION:The joint having the tack bead 3 existing on the root 4 of a groove is subjected to a welding along the root 4 with rotating the arc 6 at the wire tip at high speed with rotating an electrode nozzle 5. At this time, the arc voltage waveform or welding current waveform is integrated within the range of <=+ or -45 deg. centering around the front point Cf and rear point Cr in the welding progressing direction and the respective sum (SCf + SCr) is found. On the other hand, the sum of the integration values (SR + SL) is similarly found as to the right R and left side in the progressing direction. These differences are controlled by comparing with the preset reference value. With this method, the tack bead can be detected with good accuracy.

Title: Limiting current type oxygen sensor
Inventor: SHIGEOKA TAKEHIKO
IPC: G01N27/41
Filed: 1993-09-13
Abstract: PURPOSE:To improve the responsiveness and durability of a sensor by providing a spatial spacer for reducing electrode space at a position opposite to a cathode electrode on a sealing plate at the side of a glass spiral spacer. CONSTITUTION:When rated voltage is applied from a heater control section to a heater 6 for heat application, the heater 6 is self-heated, and maintains a solid electrolyte plate 1 at high temperature for the activation thereof. In this case, when voltage is applied across cathode electrodes 3 on both sides of the plate 1 and an anode electrode 2 via a sensor control section, electrochemical reaction occurs for oxygen injection and release generated at the electrodes 3 and 2. At this process, the feed of oxygen to electrode space 8 is limited with an oxygen diffusion passage formed out of a glass spiral spacer 4. As a result, a saturated current characteristic appears in voltage and current characteristics, and the magnitude thereof is proportional to the oxygen concentration of atmosphere. As a spatial spacer 9 is positioned in the space 8, oxygen therein is quickly injected or released correspondingly, thereby causing limiting current to flow in a short time.

CONSTITUTION:When the Chinese character exchange key is depressed, the letter data are sent to 'furi-gana' (phonetic syllabaries attached the Chinese character to shown its pronunciation) field control part 4 and a kana/Chinese character conversion task field control part 5. From the 'furi-gana' field control part 4, the data is directly sent to Japanese input field. From the kana/Chinese character conversion field control part 5, the data is transferred to dictionary control part 6, from which candidate letter signals are returned. And then, the input of new letter data is made possible. When a correction is made to the data already converted, protection is made to the 'furi-gana' field so that new input may not be made there because the input there is already finished. In this way, Japanese sentence including Chinese character, and the 'furi-gana's' for these Chinese characters can be inputted by one operation.

Title: Steel sheet excellent in toughness in weld heat-affected zone
Inventor: KOJIMA AKIHIKO
IPC: C22C38/14
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To obtain superior HAZ toughness under a wide range of welding conditions by specifying the composition of elements. SOLUTION: Among contained elements, noteworthy elements are Ti, Mg, O, and N. Ti is incorporated by 0.005-0.030wt.% in order to form TiN grains as an essential constituent of pinning grains in sufficient amounts. Mg is the most important element and improves the high temp. stability of TiN grains by being added in combination with Ti, and its content is regulated to 0.0005-0.005wt.%. O combines with Ti and Mg, as deoxidizing elements, to form fine oxides and contributes to pinning at high temp., and its proper amount is 0.001-0.005wt.%. N is necessary for formation of TiN and refining of heated γ-grains in HAZ and incorporated by 0.002-0.006wt.%. By this method, TiN grains are dispersed finely even at high temp., and heated γ-grains in HAZ in the vicinity of bond line are refined and HAZ structure is refined, by which toughness can be improved.  This steel sheet can be effectively used, in particular, for high heat input welding with long residence time at high temp.

Abstract: PURPOSE:To easily form a thin film of beta-BaB2O4 on a substrate of any material by coating the substrate with the powder of beta-BaB2O4 and sintering the substrate to grow the beta-BaB2O4 thin film. CONSTITUTION:A soln. of barium chloride and boric acid is controlled to pH12 to precipitate BaB2O4.4H2O, the precipitate is calcined to prepare the powder of beta-barium borate (beta-BaB2O4).

The substrate is then sintered to grow the thin film of beta-BaB2O4. Consequently, as the beta-BaB2O4 applied on the substrate is grown, the powder is grown into a single crystal thin film with the C axis uniformly directed vertical to the substrate. Further, since the lattice constant of the substrate does not cause any trouble, the beta-BaB2O4 thin film is formed on any material.
